Hello Felipe,

You should be able to find support for ASN.1 in the ncbi toolkit, e.g.

> http://www.ncbi.nlm.nih.gov/Web/Newsltr/V14N1/toolkit.html


And google turned this up for me:

"The Apache ASN.1 runtime is a high performance non-blocking replacement
for the Snacc4J runtime and eventually its Java stub compiler for ASN.1.
It is designed from the ground up to work with NIO constructs like
Channels and ByteBuffers."
